PASSAGEWAY DRIVE MECHANISM FOR ARTICULATED CAR UNITS.

Application filed April 18, 1928. Serial No. 270,960.

An object ofmy invention is to provide the passageway member of an articulated car unit with means operable by the adjacent car bodies for turning the passageway member as the car bodies move relative to each other.

Anotherobject of my invention'isto provide an articulated car unit with a passage way'drive mechanlsmiuounted onv the adja cent car bodies and having a slidingcontact with a member on the side of the passageway member.

Another object of my invention is to provide an articulated car unit with a passage.- v

.member 13 to form a ball and socket joint way drive mechanism which will be operable by themovement of the car bodies relative to each other, and which. will so position the passageway member so as to maintain a free and uninterrupted passage between'the car along the lines 44 of Fig. 3 with the upper bodies.

Referring to the drawings, Fig. 1 1s a sectional plan view of a portion of an articulat-ed car unit showing-the relation of the passageway member to the adjacent car body and the passageway drive mechanism; Fig} 2 isa section taken along the lines 22 of Fig.

1 with one body removed; Fig. 3 is a plan view-similar to Fig. 1 and shows a modification of my inventlon; F1g. 4 1s a sectlon taken portions of the car bodies removed to bet ter show the invention; Fig. 5 is a section taken along thelines 55 of Fig. 1; Fig. 6 is a section taken along the lines 6+6-of Fig. 3; Figs. 7 ,"8 and 9 show by diagram means the action. of the passageway member and drive mechanism when the bodies are on a straight track, when one of the bodies is turning relative to the other, andwhen both bodies are turning. 1 Referring now in detail to the drawings where like reference characters, refer to like parts, reference character 1 indicates an articulated car unit comprising bodies 2 and 3 supported by means of bearings 4 on a comample, as shown and described in U. .8. Pat. No 1,644,394 granted October 4, 1927, to A. K. Pehrson et al., and hasopenings' 8 and '9 at opposite sides'thereof communicating with the adjacent car bodies 2 and 3.

At the side of the passagewaymember, as shown in Flgs. 1, 2 and 5, is a guide member .10 having guide portions lland 12whichare slidably en aged by the member 13 attached to the drive mechanism arms 14. These arms,

, comprise an intermediate portion and end portions formed as heads 15. One of the heads 15 is held in suitable depressions in the and the other head of the member 14 is held in similar depressions in the member 16 secured to. the adjacent vertical portions of the car bodies 2 and 3. I

l/Vhen both bodies are on a straight portion ofthe track the car bodies 2and3, passageway member 5 and passagewaydrive mechamsm are in a positionas shown b-yFigs. 1', 2, 5 and diagram Fig. 7 In this position the arms 14 cooperate with the passageway and adjacent car bodies to maintain the passage-- way openings Sand 9 of the passagewayrmemher in fixed relation to the openings of the car bodies so as to maintain a free and unin} terrupted passageway between the car bodies at all times. I

WVhen the articulated car unit is entering a curve in the track and one of thebodies such as v3 has already entered upon the curve while the other body 2 remains on "a straight portion of; the track, thecar bodies will assume a position in relation to each other-as shown by the diagram Fig. 8. With the turning of the car body 3 the'heads 15 of the arms 14 the member 13 along the member 10 attached to the passageway member causing the passageway'member 5 toturn on its base 6 a dis turning in the sockets of the members 16 push i is roughly one-half. This movement of the passageway causes the openings 8 and 9 there-- in to proportion the movement of the open ing in the one car body 3 between the two car bodies and maintains a free and uninterrupted passageway between them.

When both'car bodies 2 and 3 move relative to each other, as shown by diagram Fig.

9, the arms 14 move the slide 13 along the each of the adjacent ear member 10 to again move the passageway member so'as to proportion the movement between the two car bodies. If, as shown in 9, both bodies move an equal amount the passageway 'member will of course remain stationary relative thereto, but it will be readily apparent that a greater movement by one body than by the other wiil cause a proportionate turning of the pasasgeway member.

Figs. 3, L and 6 show a modification of my invention with the member. 10 secured to the base of the passageway member and the members ldsecured to the underframe of the car body. The movement ot'the drive mechanism and-passageway member will obviously be the same as previously described.

' Having thus described the invention what :1 claim as new and desire to secure by Letters Patent 1's: a

1. In. an articulated car unit, a passageway member, a passageway drive mechanism said mechanism comprising a member mounted in a bail and socket joint on each one of the adjacent ends of the car bodies and similarlyengaging a member slidably mounted on the passageway member.

2. In an articulatec. car unit, a passageway member a passageway drive mechanism, said 'mechanis'm comprising a eber attached by a ball and socket joint'to the under-frame ot attachedto a member slidably mounted at the base of the passageway member.

- 3.1m an articulated car unit, a passagebodies and similarly of two adjacent car bodies supported on a common truck, a passageway member pivotally mounted on said truck, between andLeX tending into said car bodies, a drive mechanism operable by said bodies controlling the turning of said passageway member, said 'mechanis 3 comprising an arm on each of the two car bodies engaging a member slidably mounted in guides at the side of the passageway member, the ends. of each ot'said' arms forming ball and socket j oints at their points of connection. v r

In an articulated car unit, ahollowcylindrical member with openings at each side thereof pivotaliy mounted on the truck common to both bodies for maintaining an uninterrupted passageway between the 311 bodies, drive mechanism for said passageway membercomprising members mounted at one end. in a ball and socket joint on eachone of the two adjacent ends of the car bodies and with the other ends of said members engaged by a member at the side. of the passageway FELIX noon.
